If carbureter loads up after considerable service, check float level. \\-onr
on lip of Iloat lever will raise float level. Before adjusting neat, be sure
float lever pin plug is firmly seated. Heset float level by bending lip of
float lever away from needle to raise level, or bend lip toward needle to lower
float level. Pend vertical lip of float only.
If motor stalls while idling, set throttle lever adjusting screw so motor runs
approximately 300 rpm. Then set idle adjustment screw as instructed above.
If these adjustments do not correct the trouble, remove idle orifice tube and
plug assembly and clean with compressed air.
If acceleration is not satisfactory, remove pump jet and clean with compressed
air. Also examine pump link setting. Pump link line three holes giving short,
medium and long strokes. If link is set to short stroke, reset to give longer
stroke to pump piston. In hot weather, high altitudes, orwhen high test gasoline
is used, connect pump link in inner hole, giving shorter stroke.
Maximum economy is secured only when breaker points, spark plugs, valves and
motor tinting are set to manufacturer's specifications. After motor is properly
tuned. the following should also be clone to insure satisfactory performance
and economy.
(a) Float level must be set as above.
(b) Ball check in step-up valve assembly must seat and move freely. \\'lien
reassembling, valve housing must be screwed in tight against seat.
(c) Step-up push rod must move freely in upper and lower guides.
(d) Step-up piston in upper casting should not bind and must be free of dirt.
